Bug Report: Terrain Tool Becomes Unresponsive Beyond Certain Coordinates

The bug occurs when working on an extremely large map—likely larger than anything attempted before. While using the terrain tool, I discovered a strange bug where, after reaching certain coordinates, the tool stops functioning. It essentially “locks up,” preventing me from selecting, filling, moving, or rotating the terrain.

However, what confuses me is that, despite the terrain selection tool becoming completely unusable beyond these coordinates, I can still create terrain using the terrain creation tools, as long as I configure them with “Grid to Terrain” and use voxel-based measurements.

The specific coordinates where this issue occurs are:

X: 1886

Y: -318

Z: 31876

Below, I will provide as much evidence and as many details as possible to demonstrate the problem.

Expected behavior

If it were functioning normally, without any issues or limitations, I would expect it to be able to generate, delete, move, or rotate terrain regardless of the coordinates. However, I am unsure whether this is actually a bug or if the terrain generator has a coordinate limit. That said, I find the latter unlikely, given that the terrain creation and sculpting tools, such as the brush tool, still work beyond these coordinates.

I have this exact same issue. I only discovered it today while working on my 60,000 stud long game map, at around -31000 on the z axis the select tool becomes erratic and unusable, all other tools seem to work fine though.

Yes, exactly, I’m glad I’m not the only one who has discovered this problem. Ironically, the selection tool becomes unusable as you say, but all the others continue to work perfectly.
